Servo gauge 854 ATG
A compact, intelligent and reliable Advanced Tank Tank Gauge As tank tank gaugin gauging g has has evolve evolved, d, the the series series 854A 854ATG TG servo servo leve levell gauge gauge has become an industrial standard all over the world. Very reliable, versatile and accurate automatic tank gauge with a minimum of moving parts, meeting all international standards, regulations and recommendations. recomme ndations. A true test of its quality is the dependability and low warranty record that the ATG A TG has has mainta maintained ined for many year years. s. The multi multi-func -functiona tionall instrume instrument nt is mod modularly ularly cons construct tructed. ed. The option slots for additional features allow connecting to a wide range of other instruments e.g. temperature-, temperatur e-, pressure-, interface measurement and more. Obviously the connectivity to various eld busses and tank inventory or host systems can easily be accomplished. Simple conguration and diagnostics are possible through through a hand held device or via conguration software. software.
